Drop down/ Overlapping Content script Problem

[druggedoncolor]

1) Script Title: Drop down/ Overlapping Content script

2) Script URL (on DD): http://www.dynamicdrive.com/dynamici...lapcontent.htm

3) Describe problem:

I am building a Drop down/ Overlapping Content script gallery for my one page website. I am using it as a content solution. However, while coding the gallery in a blank webpage I noticed that I can't apply the effect to more than one image. How can I get around this?! Here is where I am working from:
